In this episode, Martin is joined by advertising and design expert Karoline Lundberg. Karoline has always had an interest in multi-sensory branding, and the focus of her research has been in designing drinks packaging which allows visually impaired and blind consumers to feel important information about what’s inside. Given it’s estimated there are 253 million visually impaired people worldwide, Karoline says stores do not do enough for them, and wants to see that change.
